1. Professional mining still has a certain threshold, which needs professional operation and maintenance. If someone tells you that as long as you pay for the miner, the cow can wait to collect money, then this is basically a fraud project.
2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.
3. You can go to the official website of bitmainland to buy the latest ant miner. Or other mining machinery trading website. There is no mining machine transaction in Huo coin mine.
4. Hello! First of all, what kind of process do you adapt to? Therefore, it is necessary to make spectrum of the ore first, then make quantitative analysis of the corresponding valuable elements according to the spectrum analysis results, and then do beneficiation test. According to the mineral processing test, calculate the output value, mining, beneficiation and smelting cost, and calculate the profit margin of instrial proction. At this time, the equipment can be determined according to the technological process selected by the beneficiation test. The equipment must not be determined according to the experience, the suggestions of a single technician or the suggestions of the equipment factory without test basis. Too many factories built like this stop there, causing heavy losses!
5. On today's miners there are many high-quality second-hand mining machine, and there is a warranty problem, there are professional after-sales manufacturers
6. You can learn about go language + blockchain course:
from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. The go language itself pays more attention to distributed systems, and concurrency processing is relatively good, such as advertising and search, which are high concurrency servers
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.

7. Of course, today many customers choose his second-hand mining machine, the price is reasonable, the rability of the machine has not declined
8. Good second-hand mining machine in today's miners, excellent performance, rable, and provide quality assurance, the company has strong professional ability, good reputation
9. The most important thing is to ensure the safety of funds, do not pay the seller, the other side does not give you delivery, followed by the selection of reliable sellers, this line of water is too large, many of the mining machine are indivials, really run can not find, you can go to today's miner official website to understand, or publish the machine you need.
10. It doesn't matter. First of all, I'll take photos of the bar code and N / s code of your graphics card to store evidence. Second, I'll take a complete video of the graphics card as evidence. I also need to take photos when I send it by express mail. I need to see if the buyer has real name authentication and what the sesame score is. If the credit is good, I'll deliver the goods, if not, I'll cancel the transaction,
